Apexi Neo i n GS 400HELP!!
Ok guys i posted this in the 2 gs perfomance section and no help. so maybe a neloc member can help or anyone electronic savy,
I did a search and saw GS Fonzy's thread about this install but Im still confused.
I hard wired my neo in using JeffTsai's ecu pinout values and the T10-e diagram in the install manual.

the only thing i saw different with the two was the tps signal wire. so after i rewired that mix up. i thought i was golden.
problem is now when the car is running the rpms on the tach vs the rpms on the neo vary alot.
rpm on neo is usually half of the rpms on the tach.
what did i do wrong?????
i have it set up for
8 cylinders throttle ^
hotwire 1 in 1 out single in single out
rev 8000 (since you can only choose 6000 or 8000)
sensor readings are at ignition on:
IG 11.12v
In1 .48 v
In2 .01 v
Thr .60 v
Out .48 v
sorry if this has been discussed before i used search and couldnt find any help.
any help would be greatly appreciated.[/

if i remember correctly there is something with the v8's in the setting you need to change. if you are seeing an rpm signal chances are you hooked it up right.
i think this may be off:
8 cylinders throttle ^
hotwire 1 in 1 out single in single out
i want to say for some reason it needs to be on 4 cylinder.
because the sensor wires are split for each bank or something silly
look here on an sc400, cant find original thread

you may want to double check somehow before changing it and just "firing" it up.
sorry couldn't make it to the BBQ to help, but I am a licensed motorcyclist now
